SPECIFICATION formingpart of Letters Patent No. 270,802, dated January16, 183.

Application filedNovember8,1EB2. (No model.)

To all whom it may concern Be it known thatI, LORENZO DHHORNBECK, acitizen of the United States, resident of Paxton, in the county of Fordand State of Illinois, have invented a new and valuable improvement ipNeck-Yokes; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of this invention in aperspective view. Fig. 2 is a perspective detail view, showing theforked bearing. Fig. 3 is a vertical section taken through one of thethimble-irons and the end of the neck-yoke bar to which itis attached.This invention has relation to anti-friction 20. connections for theends of neck-yoke bars; and it consists in the construction and novelarrangement of the bifurcated thimble-iron and the double-forked bearingpivoted in the fork of the thimble-iron, and having laterally- 2 5separated roller-bearings extending between the branches of the forkedhearing, all as hereinafter set forth, and particularly pointed out inthe claimappendei In the accompanying drawings, the letter a 0designates the transverse neckyoke bar, to

the ends of which the thimble-irons b are attached. These thimble-ironsmay be internally threaded to engage the ends of the neckyoke bar; orthey may be fastened by means of pins passing through suitableperforations.

The outer end of each thimble-iron is bifnrcated, the upper and lowerbranches of the fork being parallel on their inside faces. Thesebranches are also perforated for the passage 40 of a strong pivot-pin,c.

01 represents the double-fork bearing, consisting of a body portion, 0,and the upper and lower forked branches, 9 and h. Each branchv is alsoconstructed with branches or arms, which are laterally arranged in suchrelation 5 that the arms of the upper branch are over the armsof thelower branch. The ends of the arms are perforated to receive theconnectingpins hearings in, on which the rollers l are placed. Theserollers are therefore held be- 0 tween the arms of the branches of thepivoted bearing in lateral relation to each other, their position beingalways at right angles to the direction of the length of the neck-yokebar,

' although the bearing d has vibratory motion from side to side on thepivot-pin c of the thimblBirOnu As the body portion 0 of the forkedbearing 61 is constructed with plane upper and lower surfaces to fit thebifurcation m of the thimbl'e-iron neatly, all oblique or wabblingmotion in theconnection is avoided, the bearing beinghel d in truerelation to the neck-yoke bar. This construction also serves to preventrat tling of the parts when the horses are moving forward, and whenbacking or going down hill 65 enables the breast-straps to adjustthemselves automatically in proper relation to the rollerbearings 1without catching on theconnectingframe or getting awry in any way.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

The neck-yoke connection consisting of the bifurcated thimble-iron b andthe doubleforked bearing d, pivoted in the fork of the 5 thimble-iron,and having laterallyseparated roller-bearings 1 between the branches ofthe forked bearing, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

LORENZO DOW HORNBEOK.
